To all 'zehom it may ooncem:

Be it known that we, JO B. Hea way and THOMAS H. snnLY citizens of theUnlted States, residing at Swainpscott, in the county of Essex,Commonwealth of Massachusetts and Maiden, in the county of Middlesex',Commonwealth of Massachusetts, respective ly,have invented certain newand usefui Improvements in Insole-Reenforcing Machines and we do herebydeclare the following to be afull clear, and exact description of theinvention, such as will enable othersskilled t ieert e which. t 'anps est make d use the same.

This invention relates to insole reenforcing machines andmoreparticularly to. n achines designedto apply-the reenforce materialto what are known as Geni insoles.

The invention is designed primarily to facilitate the application of thereenforce niaterialand to so unite it with the sole that the usualsupplemental rib tightening or en ng and molding ep rat en s l nessesary. The invention is also designed to facilitate the trimming of there'e nforcei ma ter'ial within the edge of the-feather.

For the purpose of securing the reenforce material firmly to therib orlip of the insole and of setting the lip at the proper inclina tion forsubsequent manufacturing operations, the invention, in one aspect,provides not only means for forming ahead inthe reenforce material andapplying such material to the insole but alsomeansfonbending the insolerib inward andmeans for beating the rib against the surface of the sole.More over for the trimming of the reenforce material, the invention alsoprovides a trimniing .lmife blade arranged to act on the material withinthe edge of the feather together with means for causing the cuttingstroke of the blade to take place duringand in the direction of feed.

. These and other features of the invention including variouscombinations and arrangements of parts will more fully appear from thefollowing description of a preferred embodiment of the inventionand willthen be particularly pointed out in the claims.

The invention is illustrated in the accompanyingdrawings in which Fig. 1is a right hand side elevation of a machine embody s the nvent e sie t Pe rr d rm;

FiglOantl Fig. 7 10 is a'sectional 'eleyation showing, the

feed table locking mechanism.

In the draw ngs the nvention is shown embodied in a machine havingithegeneral line of feed to cooperate witlrthe feed table inbfeeding thework These parts preferahly constructed and operated as in the machineof the Hadaway patent. The machine is also provided with a stationaryfoot 7 against which the featheris normal- 1y held by the upwardpressure of the table.

The devices for applying the reepforcen aterial also comprise an insideformer 8 operating to tuck the reenforce fabric intothe angle at thebase of the lip, an outside former 1,0 arrangedto press the fabricagainst the outside of the lip and into the angle at the outside base ofthe lip, and a pressing tool or hammer 12 arranged to press thereenforced lip down against the surface of the.

sole thereby pressing the fabric firmly against both sides of the. lipand also molding the lip so that it will stand at the proper inclinationto the sole whenthe pressure of the tool is removed. 1

During the operation on the sole the inside forming tool is moved in andpresses and holds the fabric snugly in the angle at the inside base ofthe lip and while the tool is thusholding the fabric the outsideviformns and feedingtcol ,6 reeves down and: folds ing stroke and the insideformer is again moved in and tucks the fabric into the inside angle atthe base of the lip and also against the inner side of the lip. Theoutside formcr 10 thencomes forward and the upper part of its workingface presses the upper part of the lip against the inside former, asindicated in Fig. 6, thereby bending the lip inward and pressing thefabric firmly against both sides of the lip near its top. The insideformer then retracts, and as it retracts the outside former follows itupand the lower edge of the working face forces the fabric snugly into theangle at the outside base of the lip as the top of the lip is bentfurther inward and is unsupported by the inside former. The pressingtool 12 then acts to beat the reenforoed lip firmly against the uppersurface of the sole. During the action of the pressing tool 'the feedtable is locked and rigidly support ed against the pressure of the toolby one or more of a series of locking pawls 16 arranged to underlie ashoulder 18 on the table or its carrying shaft 20. After the pressingtool has acted the inside former again comes forward and presses thefabric into the angle at the inner base of the lip preparatory to thenext downward stroke of the outside feeding former, the inward movementof the inside former being so timed that it acts upon the fabric afterthe outside former moves down sufficiently to overlie and preventvertical movement of the projecting edge of the fabric during the actionof the inside former.

By the action of the forming and pressing tools the fabric is crimped orfolded about the insole lip, and is pressed closely into the angles atthe base of the lip and 1 against the surfaces of the lip andfeather sothat its proper application and final adhesion to the sole is insured,while at the same time the lip may be bent inward and set at theinclination best suited to the performance of the subsequent operationsparticularly the sewing of the inseam.

The inside former 8 is mounted to slide vertically in ahead 22 and isnormally held in engagement with an adjustable stop screw 24 by a spring26 (Figs. 1, 2, 3 and 4). The

head 22is mounted for horizontal adjustment about a stud 28 on carrierlever 30 and its position 011 the carrier lever is determined by anadjusting screw 32 passing through a lug 34 on the head and by aclamping nut 36 on the stud 28. .Thecarrier lever is mounted to swingabout a stud 38 and is operated by a bell crank lever 4 one end of whichcarries a roll engaging a cam 42 and the other end of which is pro videdwith a slot 14 embracing a pivot block 46 on the stud 28. The parts areso adjusted that the former engages the reenforce fabric within the lipand then slides along the surface of the sole into the angle at theinside base of the lip thus ensuring the tucking of the fabric snuglyinto the angle. By adjustment of the stop screw24lthe vertical positionof the former within the head. 22

may be varied to vary the extent of the sliding movement of the formerand by ad ustment of the head horizontally on the carrier lever the pathof travel of the former can be varied to suit the soles being operatedupon and to secure the proper movement of the former into the angle atthe base of the lip andthe pressure requisite for properly pressing thefabric into the angle.

The outside former 10 is secured upon the forward end of a bar 48mounted to slide in a head 50 and actuated through a lever 52, the lowerend of which is connected withthc bar by a link 54: and the upper end ofwhich carries a roll engaging a cam 56. The guide-way for the bar 48 ispreferably so arranged that the forwardmovement of the former 10 will beat an inclination to the surface of the sole so that the lower edge ofthe former as it forces the fabric into the angle at the outside base ofthe lip will apply an effective pressure at the base of the lip tendingto bend the lip inward and give it a permanent set. In order that theforward movement of the former may be varied to secure the desiredpressure against the outside surface and base of the lip, the rear endof the link 54; is connected to the lever 52 by an eccentic stud 58adjustably secured in the end of the lever. To adjust the path ofmovement of the former so that its lower edge Will properly registerwith the angle at the outside base of the lip, the head 50 is supportedupon a pivot stud 60 and is provided with an arm 62 engaged by theadjusting screws 641-. The head may be securely clamped into adjustingposition by a clamping bolt 66 passing through a slot in the head. V

The pressing tool 12 is preferably constructcd to subject the lip to ahammering or beating action since such action is best suited to ensurethe adhesion of the fabric to the sole and to give the reenforced lipthe desired permanent set. The work engaging face of the pressing toolis also prct. erably of a length several times the length of thefeed sothat-the reeiiiorced willbe repeatedlyoperated upon by. the tool as-itly mounted on a rock shaft TZ'and is yield ingly connected therewith bya heavy coiled spring 74, one'end of which geges a bin 76 on the leverand the other end of which is connected "to a collar 78 secured t theshaft. The collar may be adjusted on the shaft to vary the tension ofthe spring and the pressure applied by the tool 12 to the lip and isheld in adjusted position by a screw 80 engaging one of a series ofnotches in the shaft.

The normal position of the lever 68 on the shaft is determined by anadjustable stop screi'v 82 arranged to engage a shoulder 84 on the shaft(Fig. 7); The rock shaft 72 is operated to raise and depress thetool 1'2through a gear segment '86 secureddo the end'of the shaft and engagedby'a gearseg inent 88 on the bell crank lever which operates the inside{former S. lllhrough this" connection the tool '12 is forced against thelip during the outward 'n'iovenieht ot the inside former to full''ret'racte'd position, the slight'movenient @of the former betweensuccess'five full retracting movement's being ins'uflicient topress thetool again'stthe lip.

The pawls '16 for "lockin'gthe feed table against downward movement aremounted upon the upper endof the bearing tor the feedtabjle 'shaft 2Oand-are provided with shoulders; of graduated heights adapted tounderlie-the should-ch18 formed by th'e'loiver edge of the table hub.The pawls are pressed forward by the springs90 :andfare i-etractedtorelease the table during the feed by cam surfaces 92i'0r1ned on'theinner-surtai-e of afhousing 9-;t which surrounds the pawls andis-supportechto turn about the )earing 96. The cam surfaces are providedwith depressions 98 which are normally in register with the tails ofthepawls and-permitthe pawls to swing inward into locking position.Theh'ousing is oscillated to retract and release the pawls through themovement of'tlie feed-pawl carryingdever 100 which is connected with thehousing through a pivot pin 102. ddhhen the feed pawl le'verIOO isadvanced to give the feed table itsfeedingnioven'ient. the housing 94.is inove d to retract the lockingnpawlsejbefore the feed paw'lxen gagesa tooth of the cooperating ratchet Wheel so that the "feed table willbe u'nlocke daand willzb'e free to move vertically when theoutside'teeding fori'ner engages thet'ea-ther ofthe sole aind willremain unlocked during the feed. :Atter the feed *hasbeen"completed,thefeed pawl lever is returned; and during its return movement the housingis'inovedto bring the depressions 98 into register with the tails of thepawls so that the pawl's are free to more in under the shoulder 18 onthe table when the table'mov'e's upward to press the feather of the soleagainst the stationary foot], and since the pawjls are of graduatedheights one of the'1n will act to rigidly lock the' table at whateverheight it may be positioned by the foot 7; Thetable' will there forerigidly supportthe s'o l'e during the operation of the inside former 8,outside former l0 and-pressing tool 12.

The means for trimming the 'recnfo'rce fabric inside the edge of thefeather coin prises a knife blade 104; which is given a four inotionmovement in the line of feed and which. acts to cut the fabric duringits n i'ove'nient in the direction of the feed; Dur

in'g each cutting str'okeof the knife thereforce cuts toward thepreviously trimmed or "Quip-(n t of the fabric so that there is littleif any tendency for the fabric to roll or fold up ahead-of the knifeedge with a resulting displacement or distortion of the fabric. In'tlieIconstrii'ction shown the knife operates during th'e' f'eedin'g ofthe work and is given its cutting movement through connection withthe-"feed fcam' lever which reciprocates the outside feeding former. Asshown in Figs; 3 an'db the knife blade is carried in the/lower end ofaknife carrying lever 106 and may be adjusted therein *by means o ffashaft 108liaving-a to'oth arranged to engage teeth formed on the blade.The blade is secured'in adjusting position by a clamping bolt llOja'ndnut 112. :The upper end of the "cutter "lever is mdunted to slidevertically on a pivot'block 114 which'is free to turn on the cain shaft"116 ofl'the machine and the lever is unoved vertically to raise andlower t-hedrnife bl'adeaby acam 118 engaging a roll 120 on therlever..The lever is swung about the cam shaft 11 6t0 advance and retract theknife vb'lade shy a pivot block. 122 engaging :a'fslot-in-the leverandcarried by a stud 124E adjustably secured in the lower-end of the "feedcam lever 126; The connections are such that :the knife blade will bedepressed and will be moved forward during the-forward movement of thefeedingiormer but -'at a greater speed and-to, a greater extent. Thecutting .blade will theretore move forward with relation to the fabricduring the feed and will trim the edge ofthefa-bric while'the fabricisfirinly held bythe feeding 'tornier, the drawing action of the knifebeingiitowa-rd the slit previou ly cut in the fabric "by the precedingcuttingstroke of the knife.
